Description

Fördervorrichtungen für getrocknete heiße Braunkohle, in welchen diese zwecks Kühlung einem Luftstrom ausgesetzt wird . Nach dem Hauptpatent erfolgt die Kühlung der in Förderschnecken bewegten heißen Braunkohle mittels Durchsaugens kräftiger Luftströme durch besondere, in den Schneckentrögen angeordnete Einströmöffnungen. Nun streift die einströmende Luft auf ihrem ganzen Wege durch die Schnecken hauptsächlich über die Oberfläche der Kohle hinweg und kann nicht auf die unteren Schichten wirken. Die Kühlwirkung hängt also im wesentlichen von dem Verhältnis der Oberfläche des Kohlenstranges zu seinem Volumen ab. Die Schnecke selbst bewirkt nur in sehr geringem Maße eine Umwälzung der Kohle. Erfindungsgemäß wird eine energische Umwälzung und ein Hochbringen auch der untersten heißen Schichten der Kohle in den kühlenden Luftstrom vorgenommen. Es geschieht dies in einfacher Weise dadurch, daß an der Schnecke in gewissen Abständen schaufelartig wirkende Ansätze, z. B. Winkeleisen o. dgl., angebracht werden. Derartige Ansätze sind an sich an Schnecken zur besseren Trocknung oder Erhitzung von Materialien bekannt. Bekannt sind auch besondere, zwischen den einzelnen Schneckengängers angeordnete löffelartige Rührer zum Zwecke einer Aufwirbelung der Kohle, um möglichst viel Staub aus der Kohle durch Absaugung herauszuholen. Dem Zweck einer energischen Kühlung dienen diese bekannt gewordenen Einrichtungen aber nicht.Conveying devices for dried hot lignite, in which these exposed to a stream of air for cooling. According to the main patent, the Cooling of the hot lignite moving in screw conveyors by means of suction more powerful Air flows through special inflow openings arranged in the screw troughs. Now the incoming air mainly brushes all its way through the snails over the surface of the coal and cannot act on the lower layers. The cooling effect depends essentially on the ratio of the surface area of the Coal strand down to its volume. The snail itself has very little effect Measure one overturning of the coal. According to the invention a vigorous upheaval and bringing up even the lowest hot layers of coal into the cooling air flow performed. This is done in a simple manner in that the screw in Approaches that act like a shovel at certain intervals, e.g. B. angle iron o. The like. Attached will. Such approaches are per se on screws for better drying or Heating of materials known. Also known are special ones between the individual Spoon-like stirrer arranged by the worm gear for the purpose of whirling up the Coal to extract as much dust as possible from the coal by suction. To the However, these well-known devices serve the purpose of energetic cooling not.

Eine Ausführungsform an einer Förderschnecke zeigt die beiliegende Zeichnung. Außer der Fortbewegung durch die Förderschnecke a wird dem Fördergut b durch eine Anzahl Schaufeln c eine Zusätzliche Hubbewegung erteilt. Die Schaufeln c sind zur Vermeidung eines größeren Antriebskraftb.edarfs der Schnecken an deren. Umfang so verteilt, daß .ein gleichzeitiger Eintritt mehrerer Schaufeln in das Färdergut vermieden wird.The accompanying drawing shows an embodiment of a screw conveyor. In addition to the movement by the screw conveyor a , the conveyed material b is given an additional lifting movement by a number of blades c. The blades c are in order to avoid a greater driving force requirement of the screws. Scope distributed so that. A simultaneous entry of several shovels into the material is avoided.

Dem gleichen Zweckkönnen, sofern das zu kühlende Fördergut auf Bändern befördert wird, über diesen angeordnete pflugscharartige Schaufeln dienen, die ebenfalls ein Umwälzen des zu kühlenden Fördergutes bewirken.The same purpose can be used, provided that the conveyed goods to be cooled are on belts is conveyed, serve over these arranged ploughshare-like blades, which also serve cause the conveyed material to be cooled to circulate.
